<p>使用<code translate="no" class="notranslate text-nowrap">.show</code>方法来控制警告提示框的可见性状态。默认不显示。</p>
<p>该<code translate="no" class="notranslate text-nowrap">.show</code>方法接受布尔<code translate="no" class="notranslate text-nowrap">true</code> 或 <code translate="no" class="notranslate text-nowrap">false</code>显示和隐藏分别警报。也可以将其设置为正整数（代表秒数）以创建自消灭警报。</p>
